    摘要: A measuring tool has a slider (3) supported to a body frame (1) and a feeding mechanism (4) for moving the slider in axial direction. The feeding mechanism includes: an outer roller (41) rotatably supported to the body frame (1); a forward feed roller (42) disposed between the outer roller (41) and the slider (3) at a position closer to a forward side of the slider (3) relative to the outer roller (41); a reverse feed roller (43) disposed at a position on a reverse side; a roller holder (45) supporting these feed rollers to allow them to move along the circumference around the axis of the outer roller; a first leaf spring (44) that biases these feed rollers toward the slider side; and a power transmitter (46) connecting the outer roller (41) to these feed rollers to transmit the rotation of the outer roller to the feed rollers.

    摘要: A head exchange system for a disc drive system for controlling the position of a head so as to cancel, during a head exchange, the previously measured offset value between the head and a track of a recording disc. The head exchange system has a head exchanger for selecting one of a plurality of heads in response to a signal from the host controller for storage of the information to the selected track of the disc. The head exchange system also has a busy signal transmitting unit for transmitting, when changing the selected head, a busy signal to the host controller for a predetermined time when a difference between the offset value for a current selected head and the offset value for a next selected head is bigger than a predetermined value. The busy signal transmitting unit has a busy table for storing a plurality of flag information between each head and the other heads and transmits a busy signal to the host controller when the difference between the offset value for the current selected head and the offset value for the next selected head is bigger than the predetermined value.

    摘要: An optical measuring machine is provided with an operating board which is provided separately from the main body of the optical measuring machine and which inputs and/or outputs measuring information and a retaining portion for removably retaining the operating board on a side surface of the main body. The operating board is ordinarily retained on the side surface of the main body, thereby enabling the reduction in the space for the installation of the measuring machine and the improvement of portability. When the operating board mounted on the side surface of the main body is difficult to use due to the positional relationship with an object of measurement, the necessity to set complicated measuring conditions or the like, it is possible to use the operating board in the state of being removed from the main body.
